Eli Manning has what Andrew Luck craves, a forever place in his franchise’s championship history. And when Peyton Manning’s precocious, prolific successor steps into Eli Manning’s house Monday night with his Colts at the start of Tom Coughlin’s urgent nine-game season, he will find a quarterback as famished to win his third championship as Luck is to win his first.

“Super Bowls aren’t something you get content with, or ‘I have enough,’ “Manning told The Post. “I guess I kinda lump it as an addiction, and you crave it even more once you’ve had a taste of it. You want to get back to the playoffs, and preparing for those playoff games, or preparing for that NFC Championship game when you know hey, there’s only a few teams preparing. Those are fun times. It’s a great feeling around the locker room, and the players, that you’re playing the most important game of your life but it’s relaxed and you’re enjoying it, having fun. You kinda want to get back to those feelings again.”

Manning captured his second ring when Luck was still at Stanford. Luck has made the playoffs in each of his first two seasons, but has yet to experience a conference championship game.

With Luck on the other side, every quarterback in the league knows that he better prepare himself for the possibility of a shootout, no matter how much faith he has in his defense. When Peyton returned to Lucas Oil Stadium last season, Luck beat him 39-33. Peyton won the rematch 31-24 in the 2014 season opener in Denver.

“I think you always prepare for a shootout,” Eli said. “They do a good job scoring, they score a lot of points, and I have a feeling we’re gonna have to score points.”

Luck puts immense pressure on a defense, with his head, his arm and his legs.

“He seems very well-prepared, very smart,” Manning said. “Impressed just in his play-making ability, extending plays, moving the pocket, finding guys on the scramble … seems to have a good feel for where everybody is and makes good decisions and throws the ball very accurate.”

Eli first met a young Luck at the Manning Passing Academy. Their quarterback fathers had played together with the Houston Oilers in 1982 and ’83. Young Luck, the summer before his senior year at Stanford, was a counselor.

“He came to the camp, very nice kid, threw the ball very well, and did a good job coaching the kids up,” Manning said. “He was fun to be around. Liked him from that point, rooted for him that next year, and been rooting for him since he’s been in the NFL.”

Eli, of course, gave Luck some advice.

“He was gonna be a senior in college, I think that’s what I told a lot of guys — ‘Hey, enjoy being a senior. Enjoy being a captain. Enjoy the moments of playing college football.’ ”

Eli watched Luck throw at the Academy.

“He threw the ball well and moved well,” Manning said. “It was very natural throwing the football. It looked very simple for him, and had a feeling he would have great success.”

The Giants (3-4) waited 11 years for a franchise quarterback who could replace Phil Simms. The Colts waited about 30 seconds for their franchise quarterback to replace Peyton.

“Obviously Indianapolis, that organization did their homework well,” Eli said, “and to have Peyton for as many years as they did and have great success. … They’ve gotten used to that winning culture. And with Peyton’s [neck] injury going on, had some uncertainty, and they thought they had a good quarterback with Andrew Luck in the draft, and the possibility of getting him with the first pick. They got a good one.”

It is no easy job, being the face of an NFL franchise. In any market. But especially this market. Eli enjoys being the franchise quarterback.

“I enjoy being the quarterback of the New York Giants,” Eli said. “I’ve enjoyed every second of it for going into 11 years. I consider it a great privilege, and something I’m proud of and I work hard at.

“I want to keep my job for a long time.”

Before he can worry about how long he’ll play, he’ll have to worry about the nine-game season that begins with Luck, and follows at Seattle, home to San Francisco and home to Dallas.

“I think we got a good shot,” Eli said. “I think with this year, it’s been a little different, we got a lot of rookies playing for us and starting for us. Also a lot of just new guys, kinda with their first time getting extensive playing experience. And so those first seven games, we had some ups, and we had some downs. But now, after seven games, we kinda don’t need the downs anymore.”

Luck and Eli are as humble as it gets. Eli chuckles when asked if he has any thoughts about how lucky Giants fans are to have him as their franchise quarterback.
